The periodic table of elements contains groups of elements that have very similar reactivity. This repetition in behavior is due to similarities in the valence electron configurations of the atoms within a particular group. First, (i) define what valence electrons are. Next, (ii) write the full and core electron configurations of neutral oxygen (O), sulfur (S), and selenium (Se) atoms. Then, (iii) underline the valence electrons in each of these configurations. F
